When day and night are equal around the world (North and South Hemisheres) it is called a equinox. In a year that happens twice, once in the Spring which called a Spring Equinox and once in the Fall which is called a Fall or Autumn Equinox. Spring Equinox occurs on March 21 and Fall or Autumn Equinox occurs September 22
